DRILL-HOE.

SPECIFICATION forming part of Letters Patent No. 339,154, dated April 6, 1886.

(No model.)

struction and combination of devices that will be more fully hereinafter set forth, and particularly point-ed out in the claims.

In the drawings, Figure lis an elevation of a drill-hoe with my improvement attached thereto. Fig. 2 is a vertical section ot' the same.

A represents a drill-hoe, which is of the ordinary construction, and to the lower end of which is attached thc usual shoe or shovel, I3.

O represents a standard, which is provided at its upper end with a vertical slot, D, and at a suitable distance below the slot D with a circular opening, E, which is considerably larger in diameter than the transverse diameter of the slot. From the lower end ofthe standard C, on the outer side thereof, projects a spindle, F, and above the spindle, at the inner end thereof, is formed a segmental flange, G. As a matter of choice, I prefer to form the standard, flange, and spindle of a singlepiece olmetal; but they may be otherwise constructed, if preferred. This standard is secured to one side of the drillhoe, near the lower end thereof, by means of abolt, I-I, which extends through the slot D, and a bolt, I, that extends through the opening E. Nuts H. and I are on the ends ofthe said bolts H and I, respectively. The nut II bears on the outer side of the standard at its outerend, but on the bolt I, between the outer side of the standard and the opposing face of the nut I, is placed a bridgebar, I, which spans the opening E, and has a slot, I, in which the shank of the bolt I works. means of the slot D and the opening E it will be readily understood that the standard may be adjusted vertically with rerelation to the drill-hoe, and its lower end moved forwardly or rearwardly thereon. By clamping the nuts II and I the standard may be secured to the drill-hoe at any desired adjustment, as will be very readily understood.

L representsla wheel, of small diameter and comparatively broad tread, which is journaled on the spindle F, and is provided with central peripheral walking studs or projections, L. A washer, M, which is provided on its inner side with a segmental flange, M, is placed on the outer end of the spindle, and the flange h' bears on the upper side of the outer end of the hub'of the wheel. Ears Ml project from the front side of the washer M, and in the space between these ears is inserted a linchpin, N, which passes down through an opening made in the outer end of the spindle, and thereby secures the wheel thereon.

The object of my invention is to provide means to enable the drill-hoe to force its way through trash--such as pea-vines or other rubbish-which may lie on the surface of the ground to be drilled; and the object ofmy invention is, further, to provide a means for regulating the depth at which the seed shall be planted.

The operation of my invention is as follows: As the drill is drawn along the wheel L, by reason of its studs L, comes in contact with the earth and `is rotated thereby, and the weight of the drill-hoe is borne by the said wheel. IVhen trash is encountered, the rotation of the wheel causes it to be swept rearwardly past the drill-hoe and broken, and thus prevents thetrash from impeding the motion of the drill-hoe by choking it up. As the weight of the drill-lioe is borne by the wheel, and as the latter, by reason of the slotted standard, may bc adjusted vertically or back and forth with relation to the drillhoe, it follows that the depth at which the latter shall run in the ground may be very readily regulatcd,and thus cause the seeds to be plant ed in the ground at any desired depth.

Having thus described my invention, I claiml. The combination, with the drill-hoe, of the standard having theslot D, the opening E, and the spindle projecting at right angles from one side of the standard, the bolt II, extending from one side of the drill-hoe and working in the slot D, the bolt I, extending from one side of the drill-hoe and working in the opening E, whereby the standard is secured to one side of the drillhoe, and may be adjusted vertically and laterally thereon, and the IOO supporting-Wheel journaled on the spindle and running alongside the hoe, substantially as described.

2. The combination, with the drill-hoe, of the standard secured on one side thereof, and adjustable vertically and laterally thereon, and the supporting-Wheel journaled on a spindle ,projecting from thclower end of the standard,

substantially as described.

3. The combination of the drill-hoe, the standard having the slot D, the opening E, and the spindle F, the slotted bridge-bar spanning the opening E, the bolt I, passed through Vitnesses:
